The **center bearing support** is strategically positioned to minimize vibration and lateral movement, enhancing ride comfort while maintaining structural integrity. This driveshaft is fully compatible with the Mustang s **RWD (rear-wheel-drive) configuration**, featuring a **slip yoke on the transmission end** for easy installation and removal, as well as a **constant-velocity (CV)-style joint on the axle end** to accommodate slight wheel movement during suspension travel. Whether you re hauling a trailer, towing a heavy load, or pushing the Mustang to its limits on the track, this driveshaft delivers **uncompromising strength, smooth operation, and long-lasting reliability**, making it an essential upgrade for enthusiasts seeking to maximize performance and durability in their classic Ford muscle car.

### **Pros and Cons of Buying a 2005 2010 Ford Mustang GT (9R33-4K145-AA) with a 4.6L 3V and Automatic Transmission**

#### **Pros**

1. **Strong Engine and Performance**

The 4.6L Modular V8 (3V variant) is a reliable and well-built engine, known for its durability and decent power output (around 290 300 hp in these models). It handles daily driving well and can be tuned for better performance if desired.

2. **Classic Mustang Styling**

The 2005 2010 Mustang GT retains the iconic '90s-inspired design with a sporty, aggressive stance. The body-on-frame construction and manual windows/doors add to its retro appeal, which many enthusiasts appreciate.

3. **Automatic Transmission Reliability**

The 4-speed automatic (4R75E or similar) is a proven Ford transmission, especially in later models (2007 ). Earlier years may have occasional shift issues, but with proper maintenance, it can last well over 100,000 miles.

4. **Driveshaft (9R33-4K145-AA) Compatibility**

This driveshaft is a direct replacement for the Mustang GT s rear driveshaft, ensuring proper fitment and functionality. It s a common aftermarket part, making repairs or replacements easier.

5. **Aftermarket Support**

The Mustang platform has a strong aftermarket presence, with readily available parts for suspension, exhaust, intake, and performance upgrades. Tuning options (like Holley, Link, or standalone ECU solutions) can extend its lifespan and improve performance.

6. **Lower Running Costs (Compared to Modern Mustangs)**

Parts are cheaper than those for newer models, and labor costs are generally lower. Basic maintenance (oil changes, spark plugs, etc.) is affordable.

7. **Driving Experience**

The manual steering, firm suspension, and V8 growl provide a more engaging driving experience than many modern cars. The automatic transmission is smooth and capable of handling daily driving without issues.

#### **Cons**

1. **Rust and Body Issues**

Many 2005 2010 Mustangs suffer from rust, particularly in the wheel wells, rocker panels, and undercarriage. A thorough inspection is critical rust can lead to structural weakness and costly repairs.

2. **Transmission Weaknesses (Early Models)**

The 4R75E transmission in the 2005 2006 models can be finicky, with reports of rough shifts, delayed engagement, or solenoid failures. Later models (2007 ) improved reliability, but early ones may require extra attention.

3. **Suspension Wear**

The stock suspension is stiff and not forgiving on rough roads. Bushings, ball joints, and control arms often wear out by 80,000 100,000 miles. Upgrading to poly bushings or coilovers can help, but it adds cost.

4. **Fuel Economy**

The 4.6L V8 is thirsty, averaging around **14 16 MPG highway** and **12 14 MPG city**. This is significantly worse than modern Mustangs or even smaller V6 engines.

5. **Interior Quality and Features**

The interior is basic by modern standards, with plastic trim, a simple radio (unless upgraded), and limited tech. Climate control systems can be finicky, and the seats are not as supportive as newer models.

6. **Rear Driveshaft (9R33-4K145-AA) Potential Issues**

While this driveshaft is a direct replacement, wear in the universal joints, yokes, or CV joints can cause vibrations or clunks. Inspect for play, grease leaks, or excessive wear before purchasing.

7. **Maintenance Requirements**

The 4.6L engine benefits from regular valve cover gasket replacements (every 60,000 100,000 miles), timing chain inspection (though it s an interference engine, so a broken chain is serious), and transmission fluid changes (every 30,000 60,000 miles).

8. **Depreciation and Resale Value**

These Mustangs have already depreciated significantly. While they hold value better than some domestic cars, they won t retain the same resale worth as a modern Mustang or a well-maintained classic.

9. **Noise and Comfort**

The cabin can be noisy at highway speeds, and the manual windows/doors add to the "old-school" feel, which some may find inconvenient. The ride is firm, making it less comfortable for daily commuting.

10. **Emissions and Smog Issues**

Some states have stricter emissions regulations, and older Mustangs may fail smog checks if not properly maintained. A tune-up or catalytic converter replacement may be needed.

### **Ending Conclusion**

The **2005 2010 Ford Mustang GT with a 4.6L 3V and automatic transmission** is a **great choice for enthusiasts who prioritize driving enjoyment, classic styling, and aftermarket potential** over modern convenience and efficiency. It offers a **fun, engaging driving experience**, strong engine reliability, and a **thriving aftermarket** to keep it fresh. However, **rust, transmission quirks (especially in early models), and higher running costs** make it a **less ideal daily driver** for those who want low maintenance and modern comforts.

If you **inspect thoroughly for rust, test-drive for transmission smoothness, and budget for potential repairs**, this Mustang can be a **fantastic project car or weekend toy**. For **daily use or those seeking better fuel economy and reliability**, a newer Mustang (even a used 2015 ) or a well-maintained V6 model may be a smarter investment.

### **Recommendation**

- **Buy if:** You want a **fun, drivable classic Mustang**, are prepared for **some maintenance**, and enjoy **modifying and restoring vehicles**. Prioritize models **2007 ** for better transmission reliability.

- **Avoid if:** You need a **low-maintenance, fuel-efficient daily driver**, want modern tech, or dislike **manual windows/doors and stiff suspension**.

- **Rust inspection** (undercarriage, wheel wells, frame rails).

- **Transmission test drive** (smooth shifts, no hesitation).

- **Driveshaft inspection** (no vibrations, proper greasing).

- **Engine bay** (no oil leaks, intact timing chain cover).

- **Suspension components** (no excessive play in bushings, ball joints).

- **Service records** (oil changes, transmission fluid history).

If you find a **well-documented, rust-free example with a solid transmission history**, this Mustang can be an **excellent purchase** for the right owner. Otherwise, consider a **newer Mustang or a different platform** for a more hassle-free experience.
